Evaluator¶
This section contains answers to the most important questions regarding IATA MRO SmartHub Evaluator. If anything is missing here, please let us know via our contact form (How to contact IATA?) and we will add it here.
What data shows Evaluator if a part number has different MFR?¶
The KPIs and data in Evaluator is provided and visualized on part number level as the FMV is calculated on this level. For more details about the FMV level of detail, please check the answer to the next question.
Why is the FMV calculated on part number level?¶
The FMV represents a strategic value that provides a long term orientation for all market participants where nobody has a profit or all participants have the same profit. The main implication of this definition is, that interchangeable parts are assumed to have the same value as they can be replaced without any additional costs, e.g., same part just with different MFRs.
Note
The FMV does not include an individual supply and demand situation for a market participant. The value further neglects the current individual situation / reason for parts demand.
Where can I access information about alternative and interchangeable part numbers?¶
This information is accessible in the overview section of the part search screen. In the part number details are sections for interoperabilities and modifications. If such parts exist, the respective part numbers are listed in these sections and are highlighted in blue. Clicking on of the part numbers will open the part search screen for the selected part.
Sources for information about interchangeable parts and possible modifications are customer databases and market databases.
What is the “Benchmark” function?¶
The benchmark functionality compares the performance of your company against the remaining industry. Based on the data you have contributed to the IATA MRO SmartHub and the extensive industry database included in Evaluator three KPI are calculated: potential savings, achieved savings, and total spending. The KPIs are calculated using a neutral industry reference value: the FMV. The calculation methodology and savings definition differ between the three divisions: purchase, sale, and replacement. For more details, see Benchmark.
What is the “Market statistics” function?¶
The significant number of actual transaction data (purchase order, sales order, repair orders). This data is used to provide you with statistics about market development in terms of transaction volume and price level. For more details, see Market.
What are MPV and MSV, and how do they relate to the FMV?¶
The Evaluator publishes three complementary values for every priced part & condition combination:
FMV — Fair Market Value, the strategic, neutral reference value.
MPV — Market Purchase Value, the lower bound of the typical market price corridor (what a buyer can realistically expect to pay).
MSV — Market Sales Value, the upper bound of the typical market price corridor (what a seller can realistically expect to obtain).
MPV and MSV are derived from the observed dispersion of recent transactions around the FMV. Together they describe a corridor; the FMV sits inside that corridor for parts where the data is consistent. For the full definition, see Market values: FMV, MPV & MSV.
How is FMV Quality calculated?¶
FMV Quality is a single High / Medium / Low tag combined from three underlying dimensions:
Data basis — how much real market evidence is available (FMV stage and number of transactions).
Data freshness — how recent the evidence is.
Price consistency — whether the FMV sits between MPV and MSV across the priced conditions.
The combined rating is High when every dimension is at its best level, Low when any single dimension is at its worst, and Medium otherwise. The full scorecard is described in FMV Quality scorecard.
I changed my MPV / MSV settings — why don’t I see the change?¶
MPV/MSV is recalculated on the 1st of every month. Changes you
make to the spread boundaries (min, max, override) in
Settings → Company → Evaluator are stored immediately, but they
only take effect with the next monthly calculation cycle. Existing
values stay in place until then. The “Last updated” indicator on the
settings tab shows when the values were last changed and by which
user.
Why is the FMV showing differently than before May 2026?¶
The FMV calculation methodology was revised in May 2026. The full historical record was retroactively recalculated with the revised algorithm so that all past and future values are comparable. Headline changes:
Recency weighting now uses a configurable half-life (default 180 days).
Interchangeability handling has been refined.
FMV Quality is computed on three orthogonal dimensions and stored alongside every FMV.
See FMV definition & algorithm for the methodology and FMV 2026 — Methodology deep-dive for the deep-dive. If you require values from the previous algorithm version, please contact us (How to contact IATA?).
